Gen 2 Pokemon Crystal Virtual Console Announced for 3DS!

Essentially I believe what you have to do is beat the Elite Four once, and that triggers a flag in the game which allows you to collect the GS Ball from Nurse Joy as soon as you enter Goldenrod's Pokecenter. From there you can activate the event as normally done in Japanese Crystal; that is, going to Kurt and leaving the GS Ball with him for a day, then grabbing it back from him and going to the shrine in Ilex Forest.

Here's a post on how to get Celebi! Yeah, the IVs are determined once you transfer the Pokemon to Bank. It's the same with abilities: all Pokemon from the VC games have their hidden ability once transferred, and I believe have at least 3 random IVs. Here's a post on how to manipulate the nature of your Pokemon upon transfer as well. Unfortunately, once you transfer whatever Pokeball you used to catch the Pokemon is changed to a normal Pokeball. So no HA Apriball legendaries!

Oh that's so cool! I didn't know they put the GS ball into the VC version of Crystal!
